Radial artery occlusion (RAO) is now a major concern in transradial approach (TRA). RAO limits future radial artery use for further TRA, for as a conduit during CABG, for invasive hemodynamic monitoring and for creation of arteriovenous fistula for hemodialysis in Chronic Kidney Disease (CKD) patients through same vascular approach. The effect of duration of hemostatic compression of RAO is unknown in Bangladesh. This prospective observational study was conducted in the department of Cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh (NICVD) from September 2018 to August 2019, to evaluate the effect of duration of hemostatic compression on the incidence of radial artery occlusion (RAO) after transradial percutaneous coronary intervention. A total of 140 patients underwent percutaneous coronary intervention (PCI) through TRA. RAO was defined as an absence of antegrade flow or monophasic flow or invert flow on Duplex study. In this study 70 patients (Group I) received 2 hours hemostatic compression after transradial PCI. Another 70 patients (Group II) received 6 hours hemostatic compression after transradial PCI. Radial arterial blood flow assessed at early (24 hours) and late (30 days) by color duplex study after the procedure in both groups. Early radial artery occlusion occurred in 4.3% of patients in Group I and 12.8% of patients in Group II, (p=0.04). Late radial artery occlusion occurred in 2.8% of patients in Group I and 11.4% of patients in Group II, the difference was statistically significant (p=0.04). From multivariate logistic regression analysis duration of hemostatic compression time 6 hours (p=0.01), post-procedural nitroglycerine use (p=0.03) and procedure time (p=0.03) were predictors of RAO. Shorter duration of hemostatic compression is associated with a lower incidence of early and late radial artery occlusion after transradial intervention.

Little is known from developing countries about the effects of maternal morbidities diagnosed in the postpartum period on children's development. The study aimed to document the relationships of such morbidities with care-giving practices by mothers, children's developmental milestones and their language, mental and psychomotor development. Maternal morbidities were identified through physical examination at 6-9 weeks postpartum (n=488). Maternal care-giving practices and postnatal depression were assessed also at 6-9 weeks postpartum. Children's milestones of development were measured at six months, and their mental (MDI) and psychomotor (PDI) development, language comprehension and expression, and quality of psychosocial stimulation at home were assessed at 12 months. Several approaches were used for identifying the relationships among different maternal morbidities, diagnosed by physicians, with children's development. After controlling for the potential confounders, maternal anaemia diagnosed postpartum showed a small but significantly negative effect on children's language expression while the effects on language comprehension did not reach the significance level (p=0.085). Children's development at 12 months was related to psychosocial stimulation at home, nutritional status, education of parents, socioeconomic status, and care-giving practices of mothers at six weeks of age. Only a few mothers experienced each specific morbidity, and with the exception of anaemia, the sample-size was insufficient to make a conclusion regarding each specific morbidity. Further research with a sufficient sample-size of individual morbidities is required to determine the association of postpartum maternal morbidities with children's development.

BACKGROUND/OBJECTIVE: Psychosocial stimulation (PS) and food supplementation (FS) improve development of malnourished children. This study evaluates the effects of a community-based approach of PS and FS on growth and development of severely malnourished children. SUBJECTS/METHODS: Severely underweight hospitalised children aged 6-24 months (n = 507) were randomly allocated on discharge to five groups: (i) PS, (ii) FS, (iii) PS+FS, (iv) clinic-control and (v) hospital-control. PS included play sessions and parental counselling on child development. This was done at each fortnightly follow-up visit, that is, every second week, for 6 months at community clinics. FS included distribution of cereal-based food packets (150-300 kcal/day) for 3 months. All groups received medical care, micronutrient supplementation, health-education and growth monitoring. Children's development was assessed using revised version of Bayley Scales of Infant Development at baseline and after 3 and 6 months of intervention. Anthropometry was measured using standard procedure. RESULTS: Comparing groups with any stimulation with those with no stimulation there was a significant effect of stimulation on children's mental development index (group*session interaction P = 0.037, effect size = 0.37 s.d.) and weight-for-age Z-score (group*session interaction P = 0.02, effect size=0.26 s.d.). Poor levels of development and nutritional status were sustained, however, due to their initial very severe malnutrition. There was no effect on motor development and linear growth. CONCLUSION: Children receiving any stimulation showed a significant benefit to mental development and growth in weight. More intensive intervention with longer duration is needed to correct their poor developmental levels and nutritional status.

BACKGROUND/OBJECTIVES: Adverse developmental consequences of low-birth-weight (LBW) infants have been frequently reported from developed countries where most of them are preterm. Few reports are available from developing countries, where the problem is huge and newborns are mostly term babies. We aimed to compare mental and psychomotor development and behavior of LBW Bangladeshi infants with those of normal-birth-weight (NBW) infants. SUBJECT/METHODS: Secondary data analyses from a randomized controlled trial of fish oil supplementation during pregnancy on infants' development at 10 month. There was no effect of supplementation on infants' development. All LBW (n=66) and NBW (n=183) infants were assessed for their mental development index (MDI), psychomotor development index (PDI), behavior and quality of psychosocial stimulation received at home. Socioeconomic information and anthropometric measurements were available, and bivariate and multivariate analyses were performed to examine group differences. RESULTS: LBW infants scored significantly lower than NBW infants on MDI, PDI, activity and emotional tone. They came from comparatively poorer families and had lower gestational age than the NBW infants. After controlling for possible confounders, the NBW infants had significantly higher MDI (B=2.7, s.e.=1.1, 95% confidence interval (CI): 0.6-4.8), PDI (B=3.5, s.e.=1.3, 95% CI: 1.0-6.0) and activity (B=0.5, s.e.=0.2, 95% CI: 0.1-0.9) scores. Furthermore, in a subgroup analyses, a consistent pattern of developmental delay was also noted in favor of term-LBW infants. CONCLUSIONS: In a poor-urban Bangladeshi community, LBW infants had significantly lower mental and psychomotor developments and were less active than NBW infants at 10 months of age.

BACKGROUND: Exposure to arsenic through drinking water has been associated with impaired cognitive function in school-aged children in a few cross-sectional studies; however, there is little information on critical windows of exposure. METHODS: We conducted a population-based longitudinal study in rural Bangladesh. We assessed the association of arsenic exposure, based on urinary arsenic (U-As; twice during pregnancy and twice in childhood), with the development of about 1700 children at 5 years of age using Wechsler Pre-school and Primary Scale of Intelligence [intelligence quotient (IQ)]. RESULTS: Median maternal U-As in pregnancy was 80 µg/l (10-90 percentiles: 25-400 µg/l). Children's urine contained 35 (12-155) µg/l and 51 (20-238) µg/l at 1.5 and 5 years, respectively. Using multivariable-adjusted regression analyses, controlling for all potential confounders and loss to follow-up, we found that verbal IQ (VIQ) and full scale IQ (FSIQ) were negatively associated with (log) U-As in girls. The associations were consistent, but somewhat stronger with concurrent arsenic exposure [VIQ: B = -2.4, 95% confidence interval (CI) = -3.8 to -1.1; FSIQ: B = -1.4, 95% CI = -2.7 to -0.1, n = 817), compared with that at 1.5 years (VIQ: B = -0.85, 95% CI = -2.1 to 0.4; FSIQ: B = -0.74, 95% CI = -1.9 to 0.4, n = 902), late gestation (VIQ: B = -1.52, 95% CI = -2.6 to -0.4; FSIQ: B = -1.35, 95% CI = -2.4 to -0.3, n = 874) and early gestation (VIQ: B = -1.23, 95% CI = -2.4 to -0.06; FSIQ: B = -0.92, 95% CI = -2.0 to -0.2, n = 833). In boys, U-As showed consistently low and non-significant associations with all IQ measures. An effect size calculation indicated that 100 µg/l U-As was associated with a decrement of 1-3 points in both VIQ and FSIQ in girls. CONCLUSION: We found adverse effects of arsenic exposure on IQ in girls, but not boys, at 5 years of age.

BACKGROUND: Although household food security (HHFS) has been linked to academic performance in school children, its association with early childhood development has received less attention, particularly in low-income countries. We investigated the association of HHFS with subsequent language development of children at 18 months of age in rural Bangladesh. METHODS: We followed 1439 infants born in 2002-2003 to the mothers in Maternal and Infant Nutrition Intervention in Matlab study, a large intervention trial conducted in rural Bangladesh. A HHFS scale was created from data collected from mothers during pregnancy. At 18 months, children's language (expression and comprehension) development was assessed using a Bengali adaptation of MacArthur's Communicative Development Inventory which was based on mothers' report of their children's ability to comprehend and express words in different categories. General linear regression models were used to examine the association between HHFS and language development at 18 months of age adjusting for potential confounders. RESULTS: Household food security was associated with language comprehension (B = 0.19, 95% CI = 0.09, 0.30, P < 0.001) and expression (B = 1.01, 95% CI = 1.00, 1.02, P < 0.01) at 18 months of age. Mean language comprehension and expression at 18 months of the children in higher quartiles of HHFS were higher (P < 0.05) than those of the children in lower quartiles. CONCLUSIONS: Household food security is positively associated with subsequent language development of rural Bangladeshi children. Early language development has been reported to predict later child development. Therefore, strategies to ensure HHFS status in Bangladesh and similar settings should be considered for optimum child development.

Puerperal sepsis is an important cause of maternal morbidity and mortality in developing countries. This study was undertaken to isolate and identify the anaerobic bacterial agents of puerperal sepsis among the patients admitted in Mymensingh Medical College Hospital (MMCH) during the period from July 2006 to June 2007. Endocervical swabs/secretions were collected from 50 cases of puerperal sepsis and were cultured anaerobically. Anaerobiasis was done by using gas pack (BD GAS PAK TM EZ) in anaerobic jar. Out of 50 samples, 42(84%) yielded growth in cultures. Among 42 culture positive cases, 20(40%) were Aerobic organisms and 22(44%) were mixed, i.e., Aerobic and Anaerobic bacteria. The isolated Anaerobic organisms were Peptostreptococcus 14(63.63%), Bacteroides fragilis 3(13.64%), Prevotella melaninogenica 3(13.64%) and Clostridium perfringens 2(9.09%). As a preliminary study, it was observed that anaerobic culture could be carried out with available logistic arrangement. So, it was recommended to design further study on anaerobic bacterial isolation with particular emphasis on their antimicrobial susceptibility.

BACKGROUND/OBJECTIVES: Young children with severe malnutrition usually have poor mental development. Psychosocial stimulation may reduce their cognitive deficit, but it is not usually provided. The aim of the study was to incorporate stimulation into the routine treatment of severely malnourished children in a nutrition unit and evaluate the impact on their growth and development. DESIGN: Time-lagged controlled study. SETTING: Nutritional Rehabilitation Unit (NRU) in ICDDR,B Dhaka Hospital. METHODS: Severely malnourished children, aged 6-24 months, admitted to the NRU were enrolled. All received standard nutritional care. A control group of 43 children was studied initially, followed by an intervention group of 54 children. The intervened mothers and children participated in daily group meetings and individual play sessions for 2 weeks in hospital and were visited at home for 6 months. Children's growth was measured and development assessed using the Bayley Scales of Infant Development. RESULTS: Twenty-seven children were lost to the study. In the remaining children, both groups had similar developmental scores and anthropometry initially. After 6 months, the intervention group had improved more than the controls did by a mean of 6.9 (P<0.001; 95% CI: 3.9, 10.0) mental and 3.1 (P=0.024; 95% CI: 0.4, 5.7) motor raw scores and a mean of 0.4 (P=0.029; 95% CI: 0.1, 0.8) weight-for-age z scores, controlling for background variables. CONCLUSION: Psychosocial stimulation integrated into treatment of severely malnourished children in hospital, followed by home visits for 6 months, was effective in improving children's growth and development and should be an integral part of their treatment.

OBJECTIVE: To compare the efficacy of artemether and quinine in the treatment of severe malaria in hospitalized children. STUDY DESIGN: Open randomized trial. SETTING: Pediatric ward of a tertiary care center. METHODS: All children admitted with clinical manifestations of severe malaria (as per WHO criteria) and asexual forms of Plasmodium falciparum demonstrated on peripheral smear were randomized to receive either artemether or quinine. Their clinical status and smears for parasite count were assessed every 12 hours until two successive blood films were negative. The primary end point of the study was death in the hospital and residual damage to the organ involved. The secondary end points were clearance of parasites and fever, length of time of recovery from coma and normal functions of the involved system. RESULTS: Forty-six cases completed the study protocol, 23 assigned to each drug group. Cerebral malaria was the commonest manifestation (76.1%). Mean age in artemether versus quinine group (6.6 +/- 3.5 and 5.8 +/- 2.4 years) as well as degree of parasitemia at admission (55,800 and 60,300 per microlitre) were comparable. The overall mortality rate was 23.9% with no significant difference between the two groups. Twenty six cases (56.5%) presented with more than one manifestations of severe malaria. The mortality rate was 100% with four coexisting manifestations of severe malaria. Fever clearance time in artemether and quinine group was 44.5 and 45.9 hours respectively (P >0.05). Parasite clearance time was significantly shorter in artemether group (40.9 vs. 51.9 hours; P<0.001). Recovery from coma was shorter in artemether group (34.8 vs. 38.1 hours; P<0.05). CONCLUSION: Cerebral malaria is the most common manifestation of severe malaria in children. Artemether is a good alternative drug to quinine for P. falciparum malaria. Mortality rate is directly proportional to the number of coexisting manifestations of severe malaria.

This cross sectional study compares the nutritional status and birth outcomes of 357 diabetic and non-diabetic pregnant women (203 DM and 154 NDM as control). Uncomplicated diabetic and non-diabetic pregnant women of singleton pregnancies with age range of 19-35 years were enrolled at term in BIRDEM hospital. Maternal anthropometry and neonatal anthropometric measurements were taken following standard techniques. Educational level was significantly different between the groups. The diabetic mothers were found significantly less educated (p<0.0001) compared to non-diabetic mothers. Highly significant differences were observed between the groups on mean maternal age, weight at term, height, body mass index (BMI), mid arm circumference (MAC), and hemoglobin concentration (p values for all: <0.001) with higher values for the DM group. Most of the DM pregnant mothers were either overweight (BMI: 26.0-29.0) or obese (BMI: >29.0), on the other hand most of the NDM pregnant mothers were within normal range (BMI: 19.8-26.0). DM pregnant mothers were found more anemic (45.8% vs. 23.4%; p<0.001). Mean birth weight of the infants of DM & NDM groups were 3100g +/- .500g and 2850g +/- 360g respectively. The mean chest circumference of the infants of DM mothers was found significantly higher for diabetic group (p<0.01). DM mothers delivered most of the preterm babies (16.3% vs. 5.8%; p<0.002) and macrosomy babies were found only in this group (5.9%). Significant correlation was observed between birth weight and maternal MAC (p<0.001) in both the groups. Head circumference was found significantly correlated with maternal MAC and age in the DM group only. Diabetic pregnant women were significantly different compared to the non-diabetic group by nutritional status. The DM group experienced more anemia and preterm deliveries and macrosomic babies were born only in them.

BACKGROUND: Zinc deficiency is thought to be common in young children in developing countries and some data suggest that it may detrimentally affect children's development. OBJECTIVE: Our goal was to assess the effect of zinc supplementation on the developmental levels and behavior of Bangladeshi infants. DESIGN: This was a randomized, double-blind, controlled trial conducted in Dhaka, Bangladesh. Three hundred one infants aged 1 mo were randomly assigned to receive either 5 mg elemental Zn or placebo daily for 5 mo, and subsequent growth and morbidity were observed. For the present study, developmental levels were assessed in a subsample of 212 infants at 7 and 13 mo of age with use of the Bayley Scales of Infant Development, and the infants' behavior during the tests was observed. The children's social backgrounds, weights, and lengths were also recorded. RESULTS: The children's nutritional status was generally poor. The zinc-treated group had slightly lower scores on the mental development index of the Bayley Scales than did the placebo group (beta = 3.7, SE = 1.3, P < 0.005). This effect remained significant when nutritional status and social background were controlled for. No other significant differences between groups were noted. CONCLUSIONS: The mental development index scores of the zinc-treated group were slightly but significantly lower than those of the placebo group. This finding may have been due to micronutrient imbalance. Caution should be exercised when supplementing undernourished infants with a single micronutrient.

Iodine supplementation before pregnancy in iodine-deficient women prevents cretinism and neuromotor deficits in their offspring. It is unclear whether iodine supplementation benefits cognitive function in iodine-deficient school-aged children. We therefore conducted a double-blind, randomized, controlled trial of the effects of iodized poppy seed oil (Lipiodol) on cognitive and motor function and weight gain of iodine-deficient school children. The study was conducted with 305 children in grades 1 and 2 from 10 primary schools in two iodine-deficient areas in Bangladesh. The children were stratified by school and grade and randomly assigned to receive 400 mg of oral Lipiodol or a placebo. All children were given a battery of cognitive and motor function tests and had their weights, serum thyroxine (T4) and thyroid-stimulating hormone (TSH) and urinary iodine levels measured before and 4 mo after the intervention. On enrollment, both groups were moderately iodine deficient (median urinary iodine values: placebo group = 3.3 micromol/L, n = 148; iodine group = 3.1 micromol/L, n = 152; goiter prevalence in both groups >95%). However, their T4 and TSH levels were within the normal range. After 4 mo, there was a significant treatment effect on urinary iodine levels (P < 0.0001), but the levels of the treated group were still below normal (median = 7.9 micromol/L). No significant differences were found in T4 and TSH levels, weight gain, cognitive or motor function. The findings suggest that Lipiodol supplementation in moderately iodine-deficient children with normal T4 levels is unlikely to benefit their cognitive function. However, it remains possible that other iodine preparations may have benefits.

Iodine deficiency in pregnancy leads to poor cognitive function in the offspring; however, the effect of concurrent iodine deficiency on school-aged children is not clear. Several studies have shown that school children in iodine-deficient villages have poorer cognitive function than children in iodine-sufficient villages. However, villages differ in many factors that may also detrimentally affect children's development. In addition, the children's nutritional and health status has not usually been taken into account. In this study, we compared the cognitive function and school achievement levels of 170 children who had recently had low thyroxine (T4) levels [T4 = 45 nmol/L (hypothyroid)] with children who had not had low T4 levels [T4 >/=70 nmol/L (euthyroid)]. The children were matched for school and grade level and came from the same iodine-deficient regions in rural Bangladesh. They were given a battery of cognitive, motor and school achievement tests. We also measured their nutritional status, examined their stools for geohelminths and assessed their home environments. A factor analysis of cognitive and motor function tests yielded two factors, a general cognitive factor and a fine motor factor. The children's height and arm circumference, experience of hunger, parental characteristics and stimulation in the home made independent contributions to their test scores. Controlling for these variables, the hypothyroid children performed worse than the euthyroid children on reading and spelling and the general cognitive factor. These findings indicate that a large number of disadvantages including hypothyroidism are related to the poor development of these children.

A study was conducted on 23 patients on various grades of cervical cancer, selected purposely from Dhaka Medical College Hospital. Vitamin A and E level of this histologically proved cases showed mean serum level of vitamin A was 0.41 +/- 0.19 and that vitamin E was 4.21 +/- 2.15, and these low level was constant in all Histopathological grading of cervical cancer. Contraceptive user and smoker had very low level of vitamin A and E. Majority (51%) of the cases, were from lower middle class and 49% were from lower class, seventy seven percent were illiterate, 97% were married before 18 years, 57% had more than 6 children, 71% did not use contraceptive. The availability of vitamin A rich food were within reach of lower income group, than the food source of vitamin E which are usually of animal origin. It is concluded that in cervical cancer had low level of antioxidant vitamins A and E. Further study is indicated for understanding detail antioxidant nutrients role in aetiopathology of cervical cancer in Bangladesh.
